摘　　要：设计一种垂直剖面采水的自动返回式采水器,其机械机构由配重体的悬挂或释放装置及采水瓶关闭采水机构组成。配重体的悬挂或释放未采用螺纹密封和螺纹承重,动作由密封仓内电机的驱动转动和壳体端盖上的挂钩脱钩实现。采水瓶的关闭不涉及步进电机的转动,由电磁阀的通电实现。实践表明,采水器的机械设计结构简单有效,保证密封,操作方便。A new auto-return water sampling device （ARWAD） was developed to collect a series of water column samples from selected depths in lakes and sea. The mechanical system of ARWAD consisted of the following two parts： （1） weight attachment loading-unloading system that was a combination of a drive-rotary system and a trip- ping bar system, and （2） bottle firing mechanical system that was electronically triggered through its corresponding solenoid valve. The ARWAD mechanical design had been proved simple, effective and easy to handle.
